How to put freon in my p12A
This should only be performed by a trained service technician. Not only is this potentially dangerous to the untrained person, but there is also a high potential to damage the equipment further if not charged properly.
The charge is to be metered into the suction line up stream of the compressor (charge liquid only if a blended refrigerant is used).
Most self contained unites will not have pressure taps to charge yourself, the would have to be added and soldered in aftermarket.
If in fact you had pressure taps, you will need a set of refrigeration gauges. Refrigerant needs to be weighed in, usually in ounces for a small unit. Charge is critical on these types of systems, just an ounce or two off can make a very big difference. You also need to know what type of refrigerant the unit requires, this is usually found on the name plate of the unit along or near the refrigerant charge the factory put in.
Also, if the unit entirely lost its charge, it would need to be evacuated to a deep vacuum to get all of the air out of the system. Without doing this you are wasting time and money as air in a system will create very big problems.
Furthermore, you need to make sure there is enough oil in the system, and without giving a reason or amount of refrigerant lost from the unit it is hard to give you an exact plan of action.
